✦ Synopsis
Hypsochromic shifts produced by substitution in non-alternant aromatic hydrocarbons can be interpreted in terms of simple molecular orbital theory. On that ground, the NH 3 + radical is best suited to bring about hypsochromic shifts. However, no such effect has been observed in fluoranthene, which therefore behaves like an alternant hydrocarbon. This could be ascribed to the reduced conjugation between the benzene and the naphthalene nuclei in this molecule.
